To C03/ whom it' may concern: Be it known that I, MAURICE BIDEAU, a

" vcitizen of the Republic of France, residing at Paris, 16 CitedAntin,agent'of the Socit Ame des Aciries et Forges .de Ferminy, have inventedcertain new and useful Improvev ments irl Jointed-Spindle Axles, oiwhich the vhelm in two integral parts 2 and 3, through ject of theinvention is to so mount or itthe saidv axle that it will allow of aball bearing ortvasher being arranged between the body part ofthe axleand the spindle around the studef the vertical joint of these parts insuelte manner as to avoid any injurious iuovehff/nt out of theprependicular with respect to the said stud. A .OneA embodiment of this`invention is shown in the accompanying drawing in l which;

Figure 1 is a vertical sectional view on the ,aXi'al line ol' thespindle, Fig. 2 is a plan wiew, partly in section on the axial line ofthe spindle, partly on' a plane above the body part of the axle gand'Fig. 3 is an elevation ol the inner side ofthe spindle, the bodypart oi .the axle and the joint stud being removed.

The body-part 1 of the axle terminates in a which passes a vertical.joint stud 4.: The upper part 2 oi' the helm transmits to the spindlethe vertical pressure-resulting from 35? the load on the axle: The lowerpart 3 relieves the upper part 2 through its connection with the latterby means of the stud 4, dowelepl at 5 and 5, in each of the said parts.lThe parts 2 and 'v3 are, furthermore, subjected to the strain due tothe reversing coupling on account of the distance there is between theplane of the wheel and the joint stud 4; the

part 2 operating in favor of the compression and the part 3 in favor ofthe extension.

The spindle v7 is provided, toward the aigle, with three eyelets orapertures S, 9, 10 which 'surround the studv 4, and between which theparts 2 and 3 oli the helm or block are enfgaged. The eyelets 8 and 10.are for .the purpose of resisting the reversing coupling, while thecentral eyelet 9 is only subjected to the vertical pressure due tothejload on the axle and transmi ted by a crown of balls 11 located in aball-race b etweenthe part 2 and the eyelet or a erture 9. rlhe eyelets8 and .10 bear lateral y on the joint stud 4 through the medium of ballor roller bearings 12 and 13 or of simple bronze or otherjournals.

The frictional parts and the ball bearings are protected against dirtand dust by felt or other `washers 14 and any kind of suitably shapedmetal washers 15. Furthermore, Stoppers or caps 16, 417, secured in anysuitable manner on the eyelets or apertures 8 and 10, as for instance bybeing screwed and doweled maintain the ball-bearings in place and closethe orifices of the said apertures.

The upper stopper or cap is provided with a screw-threaded hole 18, inwhich is secured in place a lubricator (not shown), and the stud 4 ispierced by suitable ducts which distribute the lubricant as andwhere itmay be required.

The eyelets 8 land 10 carry pierced bosses 19 and 20 -designed toreceive the steering and connecting levers.

The boss 1Q only exists generally on the right hand spindle (when theSteerage is at the right) and receives thev steering lever.

The boss 20, which receives the eonnectin lever, is formed on both theright hand and the left hand spindles. v

The boss 19 may be dispensed with when the constructor uses a specialdouble lever for both Steerage and connection purposes.

The swiveling may be done either on the balls 11 in suitable ball-races21, as shown in the drawing, Vor on bronze or other metal washers. Thispart is covered -by a cap 22 and the whole is again protected by ajacket of suitable shape 23, screwed or otherwise secured to the edges24 of the spindle, with the 'eyelet or aperture 9 and the part of thehelm or block and make an air-tight joint. The

'hubs 26 of the wheels may be provided With ball or roller bearings, orwith bronze or other journals. upper eyelet'S, of the'spindle, inorder-to limit the point when impinging against the body part of theaxle. 'They are in a Vsosition out lof reach of the pebbles of the roadwhich, if the bosses were at the lower part, might get in between andinterfere with the Steerage.

On account of the above ldescribesf arrangements, the elements of theswivel can be so fitted in between the two parts or branches 2', 3 ofthe helm or block as to avoid any injurious movement out of the perpen#dicular on or with respect to the j ointpin or Two bosses 27 are formedlon the IOO ' any motive power, whether light or heavy motor cars, racingor touring automobiles, drags, busses, and the like.

Claims.

'motor-cars, the combination of the body' part of the axle terminatingat each end in a helm or block having two integral parts or Y branches,a' spindle having three eyelets or apertures, the spaces between thesaid eyelets or apertures being adapted to receive theI said parts orbranches respectively, and a stud passing throughl the three leyeletsand the two branches. 'v

2. In 'a jointed spindle axle for motor-cars,

the combination ofthe body part of the axle having at each end a helm orblock having two integral parts or branches, a stud securely lixed inthe said parts or branches, a spindle having three eyelets so arrangedas to loosely surround the said stud, ball-bearings arranged in the two'outer orendl eyelets around the stud, the two parts or branches of 1.In an axle having jointed spindles for the helm or block being engagedin the spaces between the three eyelets vrespectively and ball-bearingbetween the middle or median eyelet and the upper part or branch totransmit the vertical load of the axle to the spindle.

3. In a jointed spindle axle, the combination of the body part of theaxle, of a helm or block having two parts or branches at each end of thesaid lbody part, a spindle having three eyelets, a stud passing throughthese three eye-lets and the two parts or branehes of the helm or block,the said parts or branches being engaged between the said eyelets,ball-bearings arranged in the outer or end eyelets around the stud,caps-or stop pers adapted to close the outer orices of the outer or endeyelets; a longitudinal oil channel or duct in the stud establishing acommu-f nication between the chambers of Vthe caps, a ball-bearingbetween the middle or' median eyelet and the .upper part or branch ofthe helm or block, and a transversal oil hole in the stud establishing acommunica'tionbe! tween the said oil channel or duct and the saidball-bearing.

In testimony that I claim the foregoing as -my invention, I have signedmy name in presence of two subscribing Witnesses.
